TYPOGRAPHIC SEMANTICS OF WEBPAGES ACCESSIBLE FOR VISUALLY IMPAIRED USERS Mapping Layout and Interaction Objects to an Auditory Interaction Space
نویسنده
چکیده
Binaural sound perception allows humans to localize sound sources in space. Modern spatialization soundcards already offer the possibility to place virtual sounds in a virtual auditory environment. We use this to augment the acoustical environments of blind users with virtual auditory interaction objects („hearcons“) representing the interaction objects of a webbrowser GUI. The cursor is also represented as hearcon, e.g., by a humble bee, and allows to manipulate hearcons like normal icons, with touchpad, trackball, or mouse. Supplemented with text-to-speechor braille-output the visually impaired user can receive the textual information of a webpage including its semantics coded in its typography, topography, and topology of its components.

Haptic access to 3D objects on the web
Making a web browser haptically accessible, makes it possible also for visually impaired persons to access graphical properties such as the layout of a web browser. With haptic interaction, it will also be possible to access 3D objects (VRML or X3D files) over the internet. In the present short paper the design of such a system is described. Keyw ords : haptic, browser, 3D objects, visual impai...

متن کاملAuditory Direct Manipulation for Blind Computer Users
The use of computers today almost always requires that the user is able to see what is presented on the screen, a requirement that blind computer users are not able to fulfill. Many features of the graphical user interface are inaccessible for blind computer users; direct manipulation is one of them. Direct manipulation is a fundamental property of graphical user interfaces which makes the inte...
متن کاملDesign and Evaluation of 3D Multimodal Virtual Environments for Visually Impaired People
Spatial information presented visually is not easily accessible to visually impaired users. Current technologies, such as screen readers, cannot intuitively convey spatial layout or structure. This lack of overview is an obstacle for a visually impaired user, both when using the computer individually and when collaborating with other users. With the development of haptic and audio technologies,...
متن کاملScreen Readers Cannot See: Ontology Based Semantic Annotation for Visually Impaired Web Travellers
Travelling upon the Web is difficult for visually impaired users since the Web pages are designed for visual interaction [6]. Visually impaired users usually use screen readers1 to access the Web in audio. However, unlike sighted users, screen readers cannot see the implicit structural and navigational knowledge encoded within the visual presentation of Web pages. Therefore, in a visually impai...
